Continuous-mode SPECT is a method of data acquisition, in which the detectors are continuously rotated. The total conuts of SPECT images with continuous-mode SPECT increased 1.17 times greater compared with step-mode SPECT, because the former method can collect data without delay. The increased information resulted in improvement of the signal-to-noise ratio and resolution, and the influence of activity of surrounding organs on the target organ was reduced. When radionuclide decay during data acquisition was observed, the dacay in counts was less with continuous-mode SPECT (2.2%) than with step-mode SPECT (3.3%). Since smaller sampling angles were available in continuous-mode SPECT, the artifacts dependent on angles could be reduced.

We assessed cut-off frequency (Fc) of the Butterworth filter in myocardial nuclear imaging. The RH-2 was used as a myocardial phantom. The parameters are nuclides (^201Tl and ^<99m>Tc) and the collimaters (LEGP and LEHR). Radius direction distribution function Pr(n) was applied to SPECT images for frequency space analysis, and NMSE (Normalized Mean Squared Error) method was used for assessment in real space. In both of these method of analysis, the optimal cut-off frequency varies depending on the nuclide and collimator : Fc in use of ^201Tl are 0.245 (cycles/pixel)with LEGP, and 0.250 with LEHR. However, those in use of ^<99m>Tc are 0.25 with LEGP, and 0.27 with LEHR, respectively. The image spectrum varies depending also on the injected dose in ^<99m>Tc. With 185 MBq, the optimal cut-off frequency was less than with 740 MBq. We concluded that the cut-off frequency of the Butterworth filter should be changed in reconstructing images according to the collimator, nuclide, and injected dose.

In vitro fracture study of renal calculi was performed to predict the destruction of stones by extracorporeal shock wave lithotripsy (ESWL). The mineral density (MD) and mineral content (MC) were measured using dual energy x-ray absorptiometry (DEXA), which is widely used for quantitative measurements of bone salt. MD and MC values obtained from 46 calculi correlated well with the numbers of ESWL shots (r=0.0807, r=0.811, respectively).MD and MC values obtained from 26 calculi of approximately the same sizes were assessed for the strength of calculi against the shock wave, and they showed better correlation with the nymbers of ESWL shots (r=0.783, r=0.763, respectively) than the CT values (r=0.719). Thesefore, MD and MC values reflected the fragility and strength of the calculi extremely well. In addition, multivariate analysis of the MD and MC and stone thicknesses improved the prediction accuracy as compared with simple variate analysis of MD or MC in predicting the number of ESWL shots. It is suggested that the destruction of renal calcuil by ESWL can be reliably predicted using measurements of MD and MC by DEXA and stone thicknesses.

At the Saitama Children's Medical Center, the portable type digital portal imaging device (DPID), in which the detector and the tratment facility are not constructed as one body, was introduced. When it was applied to total body irradiation, the image quality under low dose conditions was examined, and its usefulness was investigated. In the investigation, when the source-detector distance (SDD) was changed from 1m to 5m, the inputoutput characteristics, noise and contrast resolution in respective modes of standard (256×256) and fast (256×128)were measured. The pixel value of 5m in relation to 1m decreased to 14%, and noise (variation coefficient) increased by 4.5 times. The pixel value of the fast mode in relation to the standard mode became 80%. Respective limits of detection according to the contrast-detail curves became 0.3% in an intensifying screen-film (S/F) system, 0.6% in the DPID at distance of 1m, and 1.2% at 5m. No difference in the evaluation between the modes was not observed. In the clinical cases, by using the fast mode for a S/F system, the images of head neck parts and a lung correction filter were clearly seen, at 1〜1.5 times of dose were obteined.

Analysis of the focal-spot size is important for the quality control (QC) program concerning a clinical X-ray film system. It is especially important in magnification radiography. In this study the focal-spot size of a microfocus X-ray tube (Toshiba, DRX-89H) was studied using a slit focal spot camera (Nuclear Associates, Roeck). The focal-spot was examined visually. Its length was 0.115mm, and its width was 0.183mm, according to the measurements obtained by the slit images. That result were not sufficient for NEMA and IEC standards. The grid bias voltage affected the focal-spot size of the three-conductor terminal X-ray tube. Therefore, we measured it according to changes in the automatic control and the manual control of the grid bias voltage which improved (minimized) the focal spot. That obtained the best grid bias voltages to correspond with the tube voltages. We improved the focal-spot size, to 0.113mm in length and 0.165mm in width.

In general radiography, there are many radiographic techniques at hospital. Therefore, it is necessary to make a technical book for each hospital. We made a electronic guide book that described positioning technique by use of personal computer. It can be observed on monitor and can be searched easily by input of arbitraly word from key board. Furthermore, we are using as a positioning book which is printed out on paper.

Unlike conventional scanning methods, the helical scan method moves the patient's couch at a constant speed while performing continuous rotational scans. The helical scan method has sesttings for speciffic parameters, not available in conventional methods. These settings have a significant on the characteristics of the images ; they may produce image suitable for diagnosis purposes, or images unsuitable for such puroises. When the purpose of a helical scan is close examination, the effective slice width must be set as thin as possible. On the other hand, when the purpose of a scan is screening the lung cavity, a wide range scan is required in a short period of time, while limiting the deterioration of contrast in the affected part. We must therefore determine appropriate settings according to the purpose of the examination. In helical scanning, we need to thoroughly investigate the following factors : the ability to scan along the axis of the body, effective slice width, slice shape and the precision of couch velocity. This report will also refer to these factors.

The clinical aspects of modern CT technology were discussed. Recent innovations of CT technology were initiated by the introduction of helical scanning which was followed by the development of various new applications including accurate beam-hardening correction, three-dimensional CT diagnosis, and real-time CT. These new CT applications are sharing same characteristics of improved patient benefits. Although current helical scanner improved CT examination, the achievements are not sufficient in terms of both spatial and temporal resolutions. On the basis of these technical backgrounds, development of area detector and corn-beam CT is urgently required.

The Next Generation High-Speed CT Scanner system is necessary to have more rapid scanning, wider coverage (for example, about 30 cm for the whole lung), and thinner slice thicknesses to improve the spatial resolution for the axial direction, with no loss of image qualuty. Electron Beam Scanner, High-Speed Helical Scanner and Cone-Beam Scanner with Two-dimensional Detectors are discussed. The Electron Beam Scanner system may be a good candidate for the Next Generation High-Speed CT Scanner system. But the shortage of the exposure dose would be a problem. The engineering to increase the tube current must be developed for such a system. For a High-Speed Helical Scanner, the X-ray tube and the gantry must withstand centrifugal force. It dose not seem to be easy. However using multi-slice detectors would be valuable to improve the resolution in the axial direction. The Cone-Beam Scanner with Two-dimensional Detectors will cover 30 cm in a few seconds. The loss of image quality may be offset by the ability to scan multiple slices simultaneously.
